Soft modes in the easy plane pyrochlore antiferromagnet
J D M Champion, P C W Holdsworth
Thermal fluctuations lift the high ground state degeneracy of the classical nearest neighbour pyrochlore antiferromagnet, with easy plane anisotropy, giving a first order phase tra…
Er2Ti2O7: Evidence of Order by Disorder in a Frustrated Antiferromagnet
J. D. M. Champion, M. J. Harris, P. C. W. Holdsworth +14
Er_2Ti_2O_7 has been suggested to be a realization of the frustrated < 111 > XY pyrochlore lattice antiferromagnet, for which theory predicts fluctuation-induced symmetry breaking…
The Kagome Antiferromagnet with Defects: Satisfaction, Frustration, and Spin Folding in a Random Spin System
E. F. Shender, V. B. Cherepanov, P. C. W. Holdsworth +1
It is shown that site disorder induces noncoplanar states, competing with the thermal selection of coplanar states, in the nearest neighbor, classical kagome Heisenberg antiferroma…
